This constitutes 2.6 per cent of total Indian earthworm fauna. Of these, 4 taxa are exotic with extra-Indian origin. Collection and environmental information on each occurrence of a species are given. The study contributes first-hand material on earthworm fauna of the study area, thus far neglected, and likely to add more native species to the existing ones, which are very specific for vermicomposting processes. KEY WORDS: biodiversity, earthworm, agro-climatic zones, Gangetic Plain, India INTRODUCTION been cleared on a large scale primarily for agricultural practices, construction and other Earthworms (folk names, include dew- developmental activities. Changes in land worm, rain worms, night crawler, angle use pattern have directly affected the worm, and Kechua, Giduala, in Uttar composition and population structure of Pradesh) are important biological resources earthworm communities in different agro- that have a tremendous potential in agro- climatic regions of the country (Blanchart ecosystems because they significantly affect and Julka, 1997; Behera et al., 1999; soil physical structures and organic matter Bhadauria et al., 2000).
